NAMEgreater_equal
- A binary function object that returns true if its first argument is
greater than or equal to its second
SYNOPSIS
#include <functional>
template <class T>
struct greater_equal; : binary_function<T, T, bool> {
bool operator() (const T&, const T&) const;
};
DESCRIPTIONgreater_equal is a binary function object. Its operator() returns true
if x is greater than or equal to y. You can pass a greater_equal object
to any algorithm that requires a binary function. For example, the sort
algorithm can accept a binary function as an alternate comparison
object to sort a sequence. greater_equal would be used in that algo‐
rithm in the following manner:
vector<int> vec1;
sort(vec1.begin(), vec1.end(),greater_equal<int>());
After this call to sort, vec1 is sorted in descending order.
WARNINGS
If your compiler does not support default template parameters, then you
always need to supply the Allocator template argument. For instance,
you have to write:
vector<int, allocator<int> >
instead of
vector<int>
If your compiler does not support namespaces, then you do not need the
using declaration for std.
